Description

[0001] JOINT APPARATUS FOR Joining Structure of Vessel [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a joint device for joining structures, and more particularly, to a joint device for joining structures that allows a relative position of joining between an upper structure and a lower structure of a ship to be adjusted.

Generally, in the process of drying a structure such as a ship or an offshore plant, various upper structures for forming a hull are coupled to a lower structure such as a column using a crane or the like.

However, in the case where the upper structure has a large area such as a deck, it is difficult to precisely control the joining position because it is not easy to secure the view and fine control of the crane.

In addition, it takes too much time to determine the coupling position, thereby increasing the standby time of the crane and the like. This is not only a cost loss, but also a risk that safety accidents are very likely to occur due to long waiting time.

Therefore, a method for solving such problems is required.

A plurality of the buffer units 250 may be provided on the upper portion of the lower structure 20 and a plurality of the buffer units 250 may be provided on the lower structure 20. In the course of coupling the upper structure 10 to the lower structure 20, The cushioning member 274 is pushed by the load and is drawn into the cylinder 272 to absorb the impact.

That is, in this embodiment, since the buffer module 270 can be driven by a hydraulic method, the buffer member 274 can be gradually lowered to provide a buffer function when a load of the upper structure 10 is applied.

6 and 7 are views showing a coupling process between the first guide unit 100 and the second guide unit 200 in the structure joining apparatus according to an embodiment of the present invention. 6 and 7, the process of joining the upper structure 10 and the lower structure 20 is as follows.

First, the upper structure 10 is lifted through a crane or the like and placed on the lower structure 20. After setting the relative positions of the upper structure 10 and the lower structure 20 within an error range, the upper structure 10 is gradually lowered.

Accordingly, the insertion portion 130 of the first guide unit 100 is inserted into the second guide unit 200. Both sides of the insertion portion 130 are brought into contact with the guide member 222 of the guide module 220 and the guide member 222 is pushed by the insertion portion 130 to enter the inside of the cylinder 224 do.

Since the inclined surfaces 132 are formed at both sides of the inserting portion 130 as described above, even if a slight error occurs in the relative positions between the upper structure 10 and the lower structure 20, The upper structure 10 can be corrected to the correct position by sliding along the guide member 222.

As described above, even if the relative position between the upper structure 10 and the lower structure 20 is shifted, the present invention can easily correct the misalignment to perform the coupling. Accordingly, it is possible to widely allow an error range with respect to the relative positions of the upper structure 10 and the lower structure 20, and quick coupling becomes possible.

Since the impact can be absorbed by the guide module 220 and the buffer module 270 (see FIG. 5) in the process of joining the upper structure 10 and the lower structure 20, the lowering speed of the upper structure 10 So that the joining process can be performed more quickly.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
